Update: Earlier this article identified Stan Adelstein as a state representative; in fact, he’s a former state representative and current state senator. Stan Adelstein is an 84 year old Republican member of the South Dakota State Senate who represents the state’s 32nd district. On August 2nd, 2016, he wrote an article titled “Attacking a patriot mother’s tears” in which he lambasted Donald Trump over the Khizr Khan situation. At the end of his article, Adelstein declared his support for Gary Johnson’s presidential campaign:
In a presidential election year when both major party candidates are so unsuited for the position, many of us are wishing for another option. Fortunately there is one: Gary Johnson, former Republican Governor of New Mexico, and his running-mate William Weld, former Republican Governor of Massachusetts.
The Johnson-Weld ticket will appear on the ballot in all fifty states for the Libertarian Party. In Johnson we have opportunity to vote for a leader whose values are in-step with our own. With Johnson on our ballot we can enter the voting booth with excitement to cast our vote for a president with the experience, heart, and judgement that this country needs.
According to Wikipedia, there are currently ten state legislators who have endorsed Gary Johnson, four of whom are members of the Libertarian Party. Johnson has also been endorsed by one member of Congress, Scott Rigell.
